A Sharp-edged orifice 10 cm in diameter, in the side of a tank having cross section 2 m square, discharges water under a constant head. The rate of inflow by which the head I kept constant is suddenly changed from 0.023 m³/s to 0.034 m³/s. How long will it take, after this change occurs, for the head over the orifice to be 2 m? Use C = 0.67.
